I have an O235L2C in my 601XL.
It has E-Mag ignitions, an Ellison throttle body, a Warp drive three bladed prop, and a remote oil filter. There nis one electric fuel pump, and one mechanical.
I would like to hear from anyone else that has a similar set up.
I have flown the airplane, but not often. I had it inspected by the FAA for certification about the time that the NTSB sent the letter squaking about the airplane being unsafe. I flew it anyway, but was not comfortable with it. I just didn't trust it.
I am happy that the airplane will be out of service for a while while I install the upgrades.
I will have a lot more confidence in this nice little airplane once I have done that.
